Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of orthopaedics novel hollow screw.
Background technique
The bone screw being often used in bone surgery at present.Bone screw is usually used in tying bone again after the fracture
It closing, bone screw usually requires to retain a period of time in human body until bone is grown after operation, for part avulsion fracture, by
It is smaller in bone, it can not hammer into mostly with screw, or even a screw can only be hammered into, it is more likely that occur because of single screw fastening force
It is smaller, cause fracture site mobile.
In conclusion problem of the existing technology is: for part avulsion fracture, since bone is smaller, can not hammer into
Mostly with screw, or even a screw can only be hammered into, it is more likely that occur causing fractures to be displaced because single screw fastening force is smaller
It is dynamic.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of orthopaedics novel hollow screw.
The utility model is realized in this way a kind of orthopaedics novel hollow screw, orthopaedics novel hollow screw
It is provided with screw cap；
The screw cap is fixed as one with stud；The screw-internal thread fit of interior tail cap stud external screw-thread and stud；
Buttock line, which is worn, to be connect in band line in tail cap；Tail cap is connect with interior tail cap stud solid in the band line；
The stud boring is provided with internal screw thread, complementary screw-threads nail tail portion setting and stud screw-internal thread fit；
Tail cap is connect with interior tail cap stud solid in band line.
Further, the screw cap top surface is provided with the cross recess that auxiliary is tightened.
Further, there are two types of the external screw thread of various outer diameter, a part is matched with stud internal screw thread for the complementary screw-threads nail setting
It closes, a part is consistent with stud external screw thread.
Further, the tail portion external screw thread of the internal screw thread of the stud and complementary screw-threads nail cooperates, when being screwed into fracture site,
Its cooperation is fastened further rather than is loosened.
Further, the buttock line being arranged with tail cap in line is connected to weave with tendon.
The advantages of the utility model and good effect are as follows: the arrangement achieves for part avulsion fracture, need to only hammer into one
The fixation to fracture site can be realized in root screw, and whole device design is simple, easy to operate while very useful, alleviates
The pain of patient effectively prevent happening built on the sand for single screw.
Detailed description of the invention
Fig. 1 is the schematic diagram of orthopaedics novel hollow screw provided by the utility model；
Fig. 2 is tail cap schematic diagram in the band line of orthopaedics novel hollow screw provided by the utility model；
In figure: 1, screw cap；2, stud；3, complementary screw-threads are followed closely；4, internal screw thread；5, tail cap in band line；6, buttock line；7, interior tail
Cap stud.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new
Type is not used to limit the utility model.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, orthopaedics novel hollow screw provided by the embodiment of the utility model include: screw cap 1,
Stud 2, complementary screw-threads follow closely 3, internal screw thread 4, with tail cap 5, buttock line 6, interior tail cap stud 7 in line, and the screw cap 1 and stud 2 are solid
Fixed one, 2 boring of stud are provided with internal screw thread 4, and the complementary screw-threads are followed closely the setting of 3 tail portions and matched with 2 internal screw thread of stud
It closes, top is arranged to sharp type, and tail cap 5 is fixedly connected with interior tail cap stud 7 in the band line, outside the interior tail cap stud 7
Screw thread can be worn with the screw-internal thread fit of stud 2, the buttock line 6 to be connect in band line in tail cap 5.
As the preferred embodiment of the utility model, 1 top surface of screw cap is provided with the cross recess that auxiliary is tightened.
As the preferred embodiment of the utility model, the external screw thread there are two types of various outer diameter is arranged in the complementary screw-threads nail 3,
A part and 2 screw-internal thread fit of stud, a part are consistent with 2 external screw thread of stud.
As the preferred embodiment of the utility model, the tail portion external screw thread of internal screw thread and the complementary screw-threads nail 3 of the stud 2
Cooperation, when being screwed into fracture site, cooperation is fastened further rather than is loosened.
As the preferred embodiment of the utility model, the buttock line being arranged with tail cap 5 in line connects to weave with tendon
It connects, plays the role of fastening.
The utility model first cooperates complementary screw-threads nail 3 with stud 2, constitutes the shape of plain screw, utilizes screw cap 1
It is screwed into fracture fixation position, until complementary screw-threads nail 3 is pierced by, complementary screw-threads nail 3 is reversely back-outed, by interior tail cap stud 7
Using the internal screw thread for being screwed into stud 2 with tail cap 5 in line, buttock line 6 and tendon braiding are connected.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
